Tips and Suggestions
- The pneumonic Roy G. Biv is an easy way to remember the colors of the rainbow. Remember we chose to omit Indigo.
- Read a book or two about rainbows before you begin this activity
- We learned that starting with the inner or outer ring (Red or purple) or placing one of each fruit at the front end of the cake will help you plan if you need to adjust size of fruit and give your child a guide for what color fruit to place.
- We also found we had to stand a few of the fruit up to fit all the colors.
Fruit Rainbow Placemat
The human eye is relatively insensitive to hue changes in the wavelengths between blue and violet, where Isaac Newton defined indigo to be;
therefore most people do not distinguish indigo from blue and violet. Due to this,
some people feel that indigo should not be regarded as a color, but merely as a hue of blue or violet.
Most people still regard it as one of Newton's named colors of the rainbow spectrum along with red, orange, yellow, green, blue, and violet.
